LIFE-BOAT.

Application filed May 7, 1915, Serial No. 26,538.

To all ywhom t may concern.'

Be it known that l, MrciLiL ZARADZKI, a subject of the Emperor of Austria, residing at Carnegie, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Life-Boats, of which the following is a specification. i

This invention relates to certainV new and useful improvements in life boats.

The primary object of this invention is the provision of a serviceable life boat especially adapted for employment upon the deck of a vessel and being so arranged that the propelling paddles thereof serve as truck .vheels for moving the boat around upon the deck.

A further object of the invention is the provision of a life boat having manually actuated propelling means, such means functionally serving as traction wheels for moving the boat along the ground or over the deck of a vessel as well as paddle wheels when the boat is in the water.

ik still further object is to provide a combined wheel and paddle member for a boat, the same being serviceable in propelling the boat through the water and in mounting the same for free movement upon a supporting surface.

lVith these general objects in View and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter more fully de scribed, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and in which like-designating characters refer to corresponding parts throughout the several views,

Figure 1 is a side elevation of the device.

Fig. 2 is a top plan view thereof.

Fig. 3 is a vertical transverse sectional view thereof.

Fig. 4 is a perspective view of one of the propeller-wheel members detached.

By referring to the drawings, it will be noted that the life boat is provided with substantially the usual form and having a rudder 11 at the stern thereof and with a plurality of seats or thwarts 12 arranged transversely within the boat. Oppositely arranged foldable outriggers 13 are ar- Specicaticn of Letters Patent.

ranged longitudinally extending hinged as at le to the opposite sides of the boat.

A power shaft 15 is transversely journaled through the boat in bearings 1G at the opposite sides thereof, the same being provided with a pinion 17 within the boat and arranged between a support 18 of the operators seat 19 and the adjacent inner side of the boat, An operating gear 20 is journaled upon a stub shaft 21 inwardly projecting adjacent the gunwale 22 of the boat, the said gear being in constant operative meshing engagement with the pinion 17 and being provided with a turn crank or handle 23 by means of which the gear, pinion and power shaft are revolved.

One of the important features of the present invention resides in the form of combined paddle and traction wheel 24 as best illustrated in Fig. l, and being operatively arranged one at each opposite side of the boat and lixedly secured to the opposite outer ends of the power shaft 15. Each of the wheels consists of a hub 25 having radially projecting spokes 26 extending therefrom, and having paddle boards 27 secured perpendicularly at the opposite outer ends of the said spokes and extending equal distances upon the lateral sides thereof. Rings or hoops 28 of any desired number, three being herein illustrated, are concentrically arranged with respect to the central journaling opening 29 of the wheel hubA 25 and are secured by suitable means such as staples 30 to the outer edges of the boards 27, while the centrally positioned hoop is also secured by staples 31 to the outer ends of the 4spokes 26.

From this detailed description of the device, the complete operation thereof will be apparent, the boat being normally inoperatively positioned upon the deck of a vessel or upon the ground mounted upon the wheels 24': as best illustrated in Fig. 1, it being understood that either end of the boat being supported, the boat may be readily pushed along upon the said wheels after the manner of a truck and thus readily launched for service. The hinged outriggers 13 will assume their folding position when the boat enters the water and sinks substantially to the depth of the said outriggers. When the boat is in the water, the same is readily propelled in the desired direction by an occupant of the boat seated upon the central seat' 19 and turning the crank` 23 which revolves the gear 2O in one direction thus revolving the pinion 17 and the power shaft l5 in an opposite direction and consequently revolving the paddle wheels 24 in the water and forcing the boat along in whichever direction it is desired. This device provides a serviceable life boat adaptable for general application and readily movable upon land and manually operable through the water.

/Vhile the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that minor changes may be made without departing from the spirit and scope of the invention as set forth in the claims.

that l claim as new is l. A life boat provided with a centrally arranged operators seat, a vertical support therefor, an operating shaft transversely journaled through the said boat and extende ing through the said support, a pinion secured to the said shaft between the said support and the adjacent side of the boat, an inwardly projecting stub-shaft secured adjacent the gunwale of the boat, an operating gear journaled upon the said stub shaft and in constant operative meshing engagement with the said pinion, an operating handle projecting from the said gear in a plane above the said seat, and combined traction and paddle wheels secured to the opposite outer ends of the said shaft.

2. A life boat provided with a centrally Copies of this patent may be obtained for ve cents each, by

arranged operators seat, a vertical support therefor, an operating shaft transversely journaled through the said boat and eXtending through the saidl support, a pinion secured to the said shaft between the said support and its adjacent side of the boat, an inwardly projecting stub shaft secured adjacent the gunwale of the boat, an operating gear ournaled upon the said stub shaft, and in constant operative meshing engagement with the said pinion, an operating handle projecting from the said gear in a plane above the said seat, paddle wheels secured to the opposite outer ends of the said shaft, and spaced traction hoops outwardly carried by the said paddle wheels and arranged concentric with the said shaft.

3. A combined paddle and traction wheel comprising a hub, radially projecting spokes carried by the said hub, transversely arranged paddle boards secured in fiat engagement adjacent the outer ends of the said spokes and extending equal distances laterally thereof, traction hoops equally spaced apart and secured to the outer edges of the said boards and arranged concentric with the said hub, and securing means between the centrally positioned one of the said hoops and the opposite ends of the said spokes.

In testimony whereof I a'l'liX my signature.
